Brake fluid almost always gets spilled on the caliper when installing a new hose, and makes the caliper appear to leak. Give the caliper a good cleaning with soap and water and see if your leak goes away.

With a braided hose and a solid master cylinder, you can apply far more pressure than with a rubber one. You can see the caliper and fork slider twisting if you pull hard on the lever, and this prssure can also make the caliper flex, making spilled fluid appear from the caliper joint.

this is what happened. its all good now, just kinda headtricked me.

i especially don't like neglecting brakes of all things. but its A okay!
